Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to a carbon fiber front fork forming mold assembly adapted to a new semi-automatic forming line. Background Technology

[0002] Traditional fork forming molds have handles welded to both ends for opening and closing. This fixed handle increases the mold's length, potentially causing interference with the furnace during the lateral transport of the mold to different furnace platforms via a lifting trolley. This necessitates manual intervention. Furthermore, each step of the traditional carbon fiber fork forming process requires human intervention: from initial mold opening, product loading, and mold closing; to transporting the mold to the lifting trolley via pulleys; to placing it on the furnace platform; inserting the air nozzle; and starting the furnace. After a certain time for forming, the process must be repeated in reverse. Therefore, traditional fork forming production lines are not only labor-intensive but also inefficient.

[0003] In addition, on traditional production lines, molds are moved into the work area by pushing and pulling with handles during the transfer process, which can easily cause relative displacement between molds, resulting in defective molded products and affecting product yield. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a carbon fiber fork forming mold assembly adapted to a new semi-automatic forming line. By utilizing a movable and retractable handle in conjunction with a pallet for support, interference with the furnace platform can be avoided during operation. This enables automatic operation on the line, allowing the pallet and mold body to automatically enter and exit multiple furnace platforms, effectively reducing labor intensity and improving production efficiency.

[0005] This utility model is achieved through the following technical solution:

[0006] A carbon fiber fork forming mold assembly adapted to a new semi-automatic forming line is provided, including a mold body formed by splicing an upper mold and a lower mold. Horizontally arranged through rods are fixed to both ends of the upper mold along its length. Through grooves are formed along the axial direction within the through rods. Two sliding rods in the width direction of the upper mold slide through the through grooves, and U-shaped handles are connected between the ends of the two sliding rods away from the upper mold. Limiting pins are respectively provided at the ends of the two sliding rods near the upper mold. The assembly also includes a tray for placing the mold body. The area of ​​the tray is larger than the mold body but smaller than the furnace platform surface. Several water-permeable holes are formed on the tray, and raised grips are provided on both sides of the U-shaped handles along the length of the tray.

[0007] This solution uses through rods fixed on both sides of the upper mold, and slide rods that connect to the handles via through grooves in the through rods. With the help of limiting pins at the ends of the slide rods, the handles can be moved and stored, effectively avoiding interference with the furnace platform. A tray with slide rails is set under the mold body, allowing the whole mold to move in and out of the production line and work area by manual pushing and pulling of the tray, which can effectively prevent mold misalignment. Water-permeable holes are opened on the tray, allowing the mold to quickly enter the cold zone pool and complete the cooling process according to the set time. This can quickly bring the mold to the temperature required for product entry, improve the operation speed, and thus ensure product yield.

[0008] Furthermore, limit protrusions are vertically fixed on each of the four sides of the tray.

[0009] Furthermore, at least two limiting protrusions are provided at intervals along the long side of the tray, and at least one limiting protrusion is provided along the wide side of the tray.

[0010] At least two limiting protrusions are spaced apart on the long side of the tray to ensure the lateral limiting effect on the mold, and at least one limiting protrusion is provided on the wide side of the tray to ensure the longitudinal limiting effect on the mold, so as to prevent the mold from falling off the tray.

[0011] Furthermore, the vertical distance between the axis of the through rod and the upper end face of the upper mold is 35mm, and the vertical distance between the end face of the through rod away from the positioning pin and the corresponding side face of the upper mold is 30mm.

[0012] Furthermore, the ends of the U-shaped handle are bent at an R-angle, with R=30mm.

[0013] Furthermore, a through hole is vertically opened 10mm inward from the end of the slide rod, and a limiting pin, made of steel rod, is inserted and fixed in the through hole.

[0014] The limit pin uses a steel rod, which is inserted into the through hole at the end of the slide rod and welded in place to prevent the slide rod from slipping out of the through groove of the through rod and to ensure the stability of the handle.

[0015] Preferably, all four corners of the tray are chamfered.

[0016] By chamfering the four corners of the pallet, a wedge-shaped clearance can be formed at the four corners. Compared with a right-angle structure, this reduces collisions and scratches during movement and ensures smooth traction.

[0017] The beneficial effects of this utility model are:

[0018] This invention features a retractable mold handle. The mold body is placed on a tray and then moved into the work area along with the tray. Before entering the production line, the operator can remove the handle to open the mold, place the product inside, arrange it, close the mold, and then push the handle back in to retract it. The operator then pushes the tray onto the automated line, and the mold automatically slides onto a lifting trolley according to the machine's preset position. The lifting trolley places the mold on the upper or lower level of a furnace platform. After molding, the mold is automatically pushed back onto the lifting trolley and into a cooling tank. Water-permeable holes on the tray allow for efficient water flow, facilitating stable immersion of the tray and mold body in the cooling water. Cooling is completed within a set time, quickly bringing the mold to the required temperature for product placement, thus increasing work speed. After cooling, the mold surface is automatically dried, and the mold is then moved to the operator's work area via an automatic slide rail. Because the handle retractable design saves approximately one-third of the time compared to traditional methods, it also effectively reduces the labor intensity of workers and improves production efficiency.

[0024] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0025] A carbon fiber fork forming mold assembly adapted to a new semi-automatic forming line includes a mold body formed by splicing an upper mold 1 and a lower mold 2. The commonly used mold size is 835 (length) * 230 (width) * 155 (height), and a movable handle is assembled on the mold of this size.

[0026] At both ends of the upper mold 1 along its length, horizontally arranged through rods 3 are fixed to its sides. Four through rods 3 are made of 45# steel, each measuring ø25*ø15*L85mm. A through groove 10 with a diameter of 15mm is formed inside each through rod 3 along its axial direction. The vertical distance between the axis of the through rod 3 and the upper end face of the upper mold 1 is 35mm. The vertical distance between the end face of the through rod 3 away from the locating pin 11 and the corresponding side face of the upper mold 1 is 30mm. Note that the welded through rods 3 and the upper mold 1 must be kept horizontal to prevent uneven extraction.

[0027] Two through rods 3 in the width direction of the upper mold 1 are respectively slidably inserted into the through groove 10 and fitted with slide rods 4. A U-shaped handle 5 is connected between the ends of the two slide rods 4 away from the upper mold 1. Limiting pins are respectively set at the ends of the two slide rods 4 near the upper mold 1. A through hole is vertically opened 10mm inward from the end of the slide rod 4, and the limiting pin is a steel rod 11, which is inserted and fixed in the through hole. The center distance between the two steel rods 11 is 256mm. At the position 10mm inward from the end of the two slide rods 4, ø10.2mm through holes are drilled vertically, and four ø10*L18mm steel rods 11 are machined, inserted into the through holes at the end of the slide rods 4 in the center, and welded and fixed.

[0028] The slide bar 4 is made of solid 45# steel with a diameter of ø14mm and a length of 675mm. Through bending and welding using specialized equipment, the slide bar 4 is 200mm long. The middle section of the U-shaped handle 5 is 215mm long, and both ends of the U-shaped handle 5 are bent with an R-angle of 30mm. It is important to ensure the horizontal and vertical alignment of the U-shaped handle 5 and the slide bar 4 during welding to prevent skewing and ensure smooth operation.

[0029] Pulling the slider 4 allows it to move 100mm. For workers of average height, the arm length is within this range, making it easier to apply force. The steel rod is selected with a diameter of 14mm to ensure a suitable grip and facilitate the application of force. This completes the assembly of the moving handle.

[0030] It also includes a tray 6 for placing the mold body, and the four corners of the tray 6 are all chamfered. The area of ​​the tray 6 is larger than the mold body but smaller than the furnace table surface. Several water-permeable holes 7 are opened on the tray 6, and raised handles 8 are provided on both sides of the U-shaped handle 5 along the length of the tray 6.

[0031] Limiting protrusions 9 are vertically fixed on the four sides of the tray 6. Specifically, there are two limiting protrusions 9 spaced apart on the long side of the tray 6, and one limiting protrusion 9 on the wide side of the tray 6.

[0032] The specific dimensions of tray 6 are 950mm long and 430mm wide, and the dimensions of the furnace platform are 1500*1500mm. This allows tray 6 to be easily placed into the furnace platform. In addition, a 30mm protrusion is made around the tray 6 to prevent the mold from falling off. Two protruding handles 8 are made at the long-direction symmetrical angle to facilitate the operator to move the mold to the semi-automatic line. After assembly according to the above description, it can be put into production on the semi-automatic line.

[0033] The mold assembly of this utility model has a retractable movable handle installed on the upper mold 1. The entire mold is placed on a specially designed tray 6, and the entire assembly is placed into the work area via the tray 6. The operator pulls out the handle to open the mold, places the product in, arranges it, closes the mold, and then pushes the U-shaped handle 5 back into the side of the upper mold 4. The operator pushes the tray 6 to move the entire assembly to the automatic line. The mold can automatically slide onto the lifting trolley 12 according to the machine's set position. The lifting trolley 12 places the mold on the upper or lower layer of the corresponding furnace platform 13 according to the designated position. After molding is completed, it can be automatically pushed from the furnace platform 13 onto the lifting trolley 12. The centrally located handle structure prevents interference between the mold and the furnace platform 13. After entering the cooling pool, the water-permeable holes 7 on the tray 6 can be used for water passage, ensuring that the whole can quickly enter the cooling water for cooling and temperature reduction. After the cooling time is completed, the water stains on the surface of the mold are automatically dried, and then it moves through the automatic slide rail. The raised handles 8 set at both ends of the tray 6 make it easy for workers to drag it to the work area. Dragging the tray 6 to move the whole is more effective than the traditional way of dragging the mold body, which avoids mold misalignment. Compared with the original method, the overall processing can be expected to save 1 / 3 of the time, greatly improving production efficiency, reducing labor intensity and improving product quality.
